The SpaceX Falcon 9 rocket make a soft splashdown in the ocean after delivering six ORBCOMM OG2 satellites to space.
A newly released video shows a view of the splashdown, which took place on July 14, in the Atlantic Ocean, on Spaceflight.com.
The July 14 launch with six Orbcomm communications satellites showed video of key milestones in the descent, such as two ignitions of the first stage to slow down the rocket.
In other news, an Atlas 5 rocket carrying DigitalGlobe’s WorldView-3 satellite, the most powerful Earth-imaging satellite yet for the commercial market, blasted off from California last Wednesday, by rocket-builder United Launch Alliance, a forced marriage between Lockheed Martin and Boeing.
WorldView-3 features a state-of-the-art multi-spectral imaging system, a high-speed data downlink operating at 1.2 gigabits per second and control moment gyroscopes that will allow ground controllers to quickly re-orient the spacecraft for on-demand observations. From an altitude of nearly 400 miles it will be able to image the entire planet as it rotates below. The satellite is capable of seeing objects just 25cm (10 inches) across and was launched by a Russian-built RD-180 first-stage engine.
The US Commerce Department, which licenses American commercial satellite imagery providers, says DigitalGlobe must wait six months before putting out any 31cm products. Previously, DigitalGlobe was only licensed to sell images with a resolution below 50 cm to the US military.
Its main competitor in Europe is Airbus Defence and Space, which have various satellites that can capture 70cm imagery (re-sampled to 50cm) with its Pleiades-HR Optical Imaging Constellation. Pléiades 1A and Pléiades 1B provide coverage of Earth’s surface with a repeat cycle of 26 days.
China will launch Gaofen-2 this year, the 2nd of five or six satellites to be launched for 1 meter Earth observation before 2016.
Then there is a raft of smaller operators with systems that generally work at 1m and above, with one or two now providing satellite video as well.
San Francisco-based Skybox Imaging, recently bought by Google, has video of Earth acquired by its small, free-flying SkySat-1 satellite.
Planet Labs, another San Francisco venture, has a “flock” of 28 nano-satellite imagers in orbit. The 28 satellites that make up Planet Lab’s Flock 1 were carried aboard Orbital Sciences’ robotic Cygnus vessel on a run to the space station. All 28 satellites orbit at an altitude of 400 kilometers, powered by solar panels. CubeSats allow scientists to measure multiple data points that would be unobtainable otherwise.
Satellite fleet operator SES has ordered its first high-throughput satellite. SES-12, recently ordered from Airbus, is scheduled for launch in late 2017 to SES’s 95 degrees east slot covering the Asia-Pacific region, with 14 gigahertz of spot-beam capacity — 70 Ku-band beams and 11 Ka-band beams. NSR’s newly released UltraHD via Satellite, 2nd Edition, forecasts over 820 channels of UltraHD content via Satellite by 2025, with Direct to Home (DTH) leading the charge.
A pair of covertly developed inspector satellites to monitor activities in geosynchronous orbit for U.S. Strategic Command blasted were launched on July 28th. The mission is scheduled to last one year.
Some 170 countries now have at least one satellite of their own and 11 nations have the capability to launch a spacecraft into orbit, said commander Gen. William Shelton, adding that with space launch also comes missile technology and the potential for anti-satellite shootdowns.
